Course outcome
At the end of the course the student will be able to:
CO 1. Design and implement codes with higher performance and lower complexity
CO 2. Be aware of code qualities needed to keep code flexible
CO 3. Experience core design principles and be able to assess the quality of a design with
respect to these principles.
CO 4. Capable of applying these principles in the design of object oriented systems.
CO 5. Demonstrate an understanding of a range of design patterns. Be capable of
comprehending a design presented using this vocabulary.
CO 6. Be able to select and apply suitable patterns in specific contexts
